$600 dollars for a bike light? Then someone thinks that $500 dollars for a light is a better deal? Have you expensive light freaks lost your minds? How much will too much for a light be? $800, $1,000, or more? You don't need to spend anywhere near that kind of money to get more then adequate lighting for a bike. I think your all trying to have a contest to see who will have the brightest light on a bicycle without regard to price; either that or some of you have such high degree of disposable income that $900 for light is pocket change.

Talk about night blindness; if your light is too bright the reflected glare off the pavement will induce night blindness so if you try to look at something away from your light you won't see it as well. Also your not suppose to either drive a car or ride a bike and look into the light spot on the road, your suppose to look beyond the edge of the light into the darkness, your not going to be able to do that if your pupils are closed! I'm 50+ years old and ride with a 12.5 watt Cygo Metro (that cost $48 by the way), and at my "advance" age have no problems with night blindness that would require anything much brighter then that-and certainly not any brighter then 16 watts.
